Contrary to their name, rare-earth magnets are not made from rare materials; they are nevertheless the most powerful permanent magnets. The term “rare-earth” originates from the 17 elements in the ...

How Does Superheating Reduce the Magnetism of Magnets? To understand how temperature might affect a magnet, you need to look at the atomic structure of the elements it is made of. Magnets are made of ...

A new kind of quantum magnet is made out of atoms only a billionth of a degree warmer than absolute zero – and physicists aren’t sure how it behaves. A regular magnet repels or attracts magnetic ...

One of the many ways scientists are working to realize the potential of nuclear fusion as a virtually inexhaustible and clean source of energy is through new and improved magnets, which confine fields ...

Researchers have shown that certain metal-organic materials can act as permanent magnets at temperatures of up to 242 °C, while remaining magnetized in external magnetic fields as strong as 7500 ...

The next generation of cutting-edge accelerator magnets is no longer just an idea. Recent tests revealed that the United States and CERN have successfully co-created a prototype superconducting ...

Ferromagnetism, the kind displayed by metals including iron, cobalt and nickel, has its origin at the atomic level. In general, a magnetic field exists in the presence of an electric current. In a ...

This activity is part of the Science Friday Sun Camp collection! The Sun generates an incredible amount of energy, energy that you can see and feel as light and heat. Other forms of energy from the ...

A World War I-era warhead and a dead blacktip shark attached to a metal hook are just some of the things magnet fishers have retrieved around the U.S. since the hobby spiked in popularity following ...
